About
AvantStay is a Los Angeles-based premium vacation rental management and hospitality company founded in 2017 that curates, designs, furnishes, and manages short-term rental properties on behalf of property owners. Unlike pure booking platforms, AvantStay operates a vertically integrated model: the company handles interior design and furnishing, property onboarding, guest experience management, housekeeping, and revenue optimization — transforming owner-supplied homes into branded, hotel-quality vacation rental properties. AvantStay targets the premium end of the short-term rental market, focusing on larger group-friendly properties suitable for family vacations, friend getaways, and corporate retreats.
Leading travel metasearch engine owned by Booking Holdings; searches 100s of sites for flights, hotels, cars. Operates KAYAK, Momondo, and HotelsCombined.
About
KAYAK is a travel metasearch engine founded in 2004 by Steve Hafner and Paul English, acquired by Booking Holdings (then Priceline Group) for $1.8B in 2013. Headquartered in Stamford, Connecticut, KAYAK aggregates flight, hotel, car rental, and vacation package results from hundreds of travel sites, enabling one-click comparison shopping. Its product suite includes KAYAK.com, the Momondo brand (acquired 2017), HotelsCombined, and a business travel management platform, KAYAK for Business.\n\nKAYAK's revenue model is primarily CPC (cost-per-click), charging airlines, OTAs, and hotels for qualified referrals rather than taking a booking commission. This metasearch model positions KAYAK as a neutral aggregator rather than a competing OTA, though it also offers direct booking through its platform in select categories. KAYAK for Business targets corporate travel managers with policy controls and expense integrations.\n\nAs a wholly owned subsidiary of Booking Holdings ($26.9B revenue FY2025), KAYAK does not report standalone financials. It remains one of the most visited travel websites globally, with over 300 million monthly searches across its brand portfolio. KAYAK's AI trip-planning features and integration with Booking.com inventory have strengthened its position as a one-stop travel research tool heading into 2026.
